Adams Rite 4900-36-101-628 Heavy Duty Deadlatch

Product Description

The ADAMS RITE 4900-36-101-628 is a heavy duty deadlatch designed for commercial door applications requiring reliable, positive latching performance. This bolt lock engages automatically on door closing and requires deliberate retraction for release, making it well suited for high-traffic entries where security and durability are priorities. The 628 finish designation indicates an anodized aluminum clear finish, a standard specification for aluminum storefront and commercial hollow metal door frames. Installation is typically performed by licensed locksmiths, security hardware technicians, or commercial door contractors familiar with mortise-style hardware.

This deadlatch is intended for commercial door assemblies, including aluminum storefront doors, narrow-stile glass doors, and similar light commercial or mid-rise building entry applications. The heavy duty classification indicates the latch mechanism is built for repeated cycle use in demanding environments such as retail entries, office corridors, and institutional facilities. Specific compatible door frame profiles and prep dimensions should be confirmed against the manufacturer documentation for this model series prior to ordering.

Installation Notes

Installation should be performed by a qualified locksmith or commercial door hardware technician.

Disconnect or de-energize any electric strike or access control components associated with the door prior to beginning work. Verify door prep dimensions and backset requirements against the manufacturer specification sheet before installation.
